Jack Sales "Dark Skies 2"
Jack is the founder of the International Dark-Sky (IDA) Association. The goal of the IDA is to make people to be aware of the importance of the loss of our dark skies. The preservation of dark skies is an important environmental concern to astronomers, of course, but also for other aspects of our biosphere. Light pollution has been shown to adversely affect circadian rhythms of sleep patterns and hormonal cycles of many living things, including us humans. There is also an environmental concurrent effect due to wasting of energy for overused urban lighting. Jack discussed these detrimental effects of "light pollution," and alternatives to reduce these effects.
Stormy Sun" by
The Sun appears to be a very stable star and compared with many other stars that would be the case. However, considering the fragile nature of life on Earth, the Sun can pose some interesting and sometimes disastrous effects to the well being of human and animal life. John explored some of the events caused by the Sun which have affected the way we live.

LHAG members enjoyed time for socializing and browsing the Astronomy displays. They learned about LHAG activities including the Binocular Interest Group and the Cosmology Interest Group. Several different types of telescopes and binoculars were on display, and many "apps" for IPAD's, iPhones, and other devices were demonstrated.

Way Through the Solar
by Anthony Oreglia
What are the most fascinating and mysterious objects in the solar system? What have volcanoes, lakes, mountains, canyons, oceans, ice sheets, craters, crevices, geysers, and rain? What have strange names and come in all shapes and sizes? What play leap frog with each other? What may be the only place in the solar system that harbors alien life forms?...... the Moons! There are now over 160 moons that have been discovered orbiting the solar system's eight planets. Anthony gave an excellent presentation about the latest discoveries concerning these remarkable solar system objects.

Meeting "The Origin of Our Moon"
by Tom Eason
Our Moon is our closest major neighbor. In many ways it is unique compared to most other Solar System planetary moons. Why is it different, and how did it get that way? How do these differences affect us? Tom discussed four different scenarios for the origin of the Moon that address the answers to these questions.

of the World?" by Chuck Pullen -
instructor at Sierra College
Hype has been building for several years over the end of the Mayan Calendar on December 23, 2012, the Winter Solstice. Some are making it into a prophecy of the end of days. Others are tying a host of conspiracies into the "Mayan Apocalypse " including UFOs, shadow governments, and the Illuminati. Chuck informed us about the real Mayan Calendar, past predictions of doom, and the business of selling the end of the world.
